Ping 为负值 (Discord.js v13)

Question

Ping outputs a negative value. I consulted the answer for a correct ping statement , and nothing seems to go wrong.

My ping command:

const Discord = require('discord.js')

module.exports = {
    name: "ping",
    description: "Test Ping to Bot",

    async run (client, message, args) {
        console.log(`${message.createdAt} | ${message.author.tag} ${message.author} : ${message}`)
        const ping = new Discord.MessageEmbed()
        .setTitle('**🏓 PING PONG! 🏓**')
        .setColor("RANDOM")
        .addFields(
            { name: 'Độ trễ của Bot', value: `${Date.now() - message.createdTimestamp}ms` },
            { name: 'Độ trễ của API', value: `${Math.round(client.ws.ping)}ms`, inline: true },
        )
        .setTimestamp()   
        message.channel.send({embeds : [ping]});
    }
}

Output:

discord.js 13.0.0-dev.t1628035429.00d5cee

Fatal amateur mistake. Never use Date.now() with non-local timestamps unless you can somehow guarantee that the server time and your computer time are exactly the same.
